Much better!
The bending is from lens distortion. In fact in some architectural photographers will even use a tilt shift lens for combat lens distortion. Take a look at this if you want to understand why that distortion happens.
A quick solution to this problem is to remove the distortion in your post processing software. Most of the modern image processing software tools have this feature. Adobe Lightroom is quite good at this.
I like that you are developing a style of images that are sleek and minimal.
I look forward to seeing your next assignments.
Nice job here. Your image meets the criteria for the assignment.
